Or different suburbs than you’re used to. The ones nearest to where I live in DC are more urban than the California suburbs I grew up in (which were by no means rural) but they were designed without sidewalks or direct routes so kids need to be comfortable biking in the street with huge SUVs and pickups passing a foot away at 40mph – unsurprisingly they don’t and that’s probably the right call because multiple times a year someone in those safe suburbs is killed at a place where their city felt street parking was more important than sidewalks.
